SOLDERINGr-IRON.

Application filed July 11 if 'o mi lwhom t may concern Be it known that l, EDGAR TAYLOR MAMAN, a citizen of the United States, and a resident ot' Ardmore, in the county oit Montgomery and State of Pennsylvania, have invented a neuT and Improved Solderinglron, oi' Awhich and exact description.

This invention relates to improvements in soldering irons, an object of the invention being to provide a soldering iron having a combustion chamber in which gas and air oi any desired pressure, either high or low, can be burned to etliciently heat the iron.

A further object is to provide an improved construction which can be readily assembled or taken apart and Which most etliciently performs the functions tor which it is intended.

l/Vith these and other objects in view the invention consists in certain novel features et construction, and combinati-ons and rangements of parts, as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings Figure 1 is a View in side elevation i1lustrating my improved soldering iron; LJnd Fig. 2 is a view in longitudinal section partly in elevation.

1 represents a tubular handle having a hand hold 2 of Wood or other suitable material thereon, and connected at one end by a coupling 3 with the iron t, the latter being preferably of the copper point type. The coupling 3 is secured on the end .of the tubular handle 1 by screw threads 5, and the iron l.t has screwthreaded engagement, as shown at 6, with said coupling.

The coupling 3 provides a combustion chamber 7 at the inner end of the iron e, and the latter is made with any number ot, tintes or recesses 8 constituting burner orifices for the combustion chamber 7.

A coupling 9 has screw-threaded engage ment, illustrated at 10, with the rear end of tubular handle 1, and this coupling 9 is provided vvith a transversely7 extending chamber 11, Which is preferably machined into the coupling and has its outer end closed by a plug 16.

Specification of Letters Patent.

, 1919. serial No. 310,173.

A rela-tively short air inlet pipe 12 comnninicates with the chamber l1 and extends beyond the coupling 9 operating as a nipple tor the attachment of an air supply hose 14. A gas pipe 13 extends across the chamber 11 and terminates at its inner end at a point slightly removed :trom the combustion chamber 7 so as to discharge the gas into the air in the tubular handle 1 permitting a thorough intermingling of the air and gas as it enters the combustion chamber. The rear end ot the gas pipe 13 extends through the coupling 9 and constitutes a nipple tor the attachment ol? a gas supply hose 15.

ln operation the air is supplied to the chamber 11 by the pipe 12 and flows along the tubular handle 1 outside of the gas pipe 13 until it reaches the end oi the pipe 13 Where it mixes with the gas, the latter being supplied through pipe 13, as above explained.

While l. have illustrated what l' believe to be a preferred embodiment olf my invention, I would have it understood that the invention is not limited to the precise details set forth as l consider myself at liberty to make such changes and alterations as fairly fall `Within the spirit and scope oi the appended claim.

I claim:

A device ci the character described, coinprising a tubular handle, an iron, a coupling connecting the handle andthe iron and form! ing a combustion chamber between them, lsaid iron having recesses therein 't'orining burner orifices, a hand hold on the tubular handle, a coupling on the rear end of the handle having a transversely extending air chamber therein, a pair of parallel pipes, one pipe relatively long extending through the coupling of the air chamber therein and into the tubular handle and ter nnnating at a point adjacent the first men tioned coupling. and the other ot said pipes relatively short and communicating With the air chamber to one side of the first-1nen tioned pipe', the outer ends of both or' said pipes constituting hose receiving nipples.
